Gear ISO Accuracy Grade Qg

Input Gear ISO Accuracy grade Qg with a dialog box.

Gear Measurement

Input minimum normal backlash and backlash tolerance. The application determines:

Mean upper normal circular tooth thickness smn
Mean upper transverse circular tooth thickness smt
Mean chordal addendum hamc
Mean upper chordal thooth thickness smnce
Mean lower chordal tooth thickness smnci
Mean tooth thickness tolerance Ts
Whole depth ht

Calculated data for measurements can be printed in a measurement sheet.

Gear Load

Input of gear load with one of the following combinations:

Power on pinion P1 kW and rotational frequency of pinion n1 Hz
Torque on pinion T1 Nm and rotational frequency of pinion n1 Hz
Torque on gear T2 Nm and rotational frequency of gear n2 Hz

Input with dialog:

Bevel Gear Forces

Input of location of bearing points and of mean mesh point P in cylindrical coordinates as in following dialog box:

Bearing Points Dialog Box

Calculation of transverse tangential force Ft, the radial force Fr and the axial force Fa in mesh point and the reaction forces in the bearings. Axial force is minimal if the outer side of spiral of driver points toward the rotation direction. If this is not the case, the application will warn that the spiral hand is not an optimal choice for the given rotation direction. Calculation output in a window view in table form as shown in next figure:
